H STIN MMJM ATTORNEYS Patented Nov. 28, 1939 v UNITED STATES PATENT OFFICE This invention relates to improvements in statistical machines and has for a principal object the provision of an adding machine having electrically operated controls associated with the keys 6 01' the adding machine for selecting for actuation one or a plurality of counters to be actuated by a power shaft in said machine.

Another object of the invention is the provision of an adding machine and a plurality of 10 counters, each of the latter being adapted to be mechanically driven synchronous with the oper-' ating cycle of the machine. a

A further object of the invention is the provision of an adding machine having electrical contacts associated with the keys, mechanically actuated counters adapted to be associated with the mechanism or the machine, and electrical devices connected in circuits with said contacts for associating the counters with said mecha- Still another object of the invention is the provision of a machine having accumulating and printing mechanisms, keys for effecting set ups in said mechanisms and a plurality of counting devices operable in synchronism with said mechanisms, and electrically operated instrumentalities for associating a device with the mechanism, one of said devices being provided for each combination of one or more of said keys.

A further object of the invention is the provision of key mechanism for listing and totalizing numerical data or the like, the provision 01' other mechanism, actuated by said first mechanism, for counting, one of said devices being provided for a each possible combination of keys, and electrically controlled means selecting said devices, whereby a statistical count is obtained as a by-product of the listings entered into said mechanism.

Other objects and advantages 01 this invention will be obvious to those skilled in the art.

In certain types of statistical work it is desired to obtain a count of the number of times any given figure may appear in a large number of items. As an example of this, a case might be taken where a light and power company wishes to make a rate study to determine how many consumers have used, for example, 10 kilowatt hours in a month, how many 11 kilowatt hours, how many 12 kilowatt hours, etc., possibly from kilowatt hours up to 1,000 kilo watt hours. By existing methods and devices such a rate study requires a great many steps and is an expensive procedure.

By means of the device, which is the subject of the present application, rate studies may be obtained as a by-product of other work which has to be done. For example, the bills must be added up to determine what total the bills for a month amount to and a rate study may be obtained as a by-product of this operation with- 6 out involving any more time than is required to enter the items into the adding machine and totalize them.

Another example of the use of the present invention is in questionnaire work. The answers to questions may be numbered with a code number and thereby the device can be caused to count how many people give answer No. 20, answer No. 506, answer No. 999, etc.

In using the device herein shown and described, a plurality of counters is associated with this adding machine, one counter for each number, figure or amount from 0 to 999. It is obvious that the number of counters may be increased or decreased in accordance with the usage to which the machine is to be put. The counters are not disturbed during the entire operation of totalizing the bills; for example; and after the operation has been completed the total counts of all of the counters is printed on a collective sheet, preferably in one operation.

Of course, it is obvious that as many printings as desired may be taken from these counters from time to time as the work progresses but it is usual to take the final totals of counts entered into these counters at the end of an operation.

This application is a continuation in part of application Serial No. 24,332, filed May 31, 1935.

While any type of adding machine may be used in connection with the relays, circuits, and counters provided the keys are provided with contacts, in the embodiment shown applicant has selected an adding machine of the Burroughs type, such as shown and described in Patent No. 1,914,401 issued June 20, 1933, to T. M. Butler.

The counters in the present application are similar to those shown in Figures 5 and 6 of the copending application with the exception that instead of being electrically actuated, the counters in the present application aremechanically actuated, and electrically selected for actuation. Referring to Figures 4 to 8, the counter, generally designated by the numeral 25, is comprised of a shaft 26 suitably journaled in a supporting plate. The shaft 26 carries a plurality of counter wheels 28, each of which is provided with an internal pawl 29 which is engaged by a keyway 39 when the counters are reset. This will presently be described.

Each counter wheel has secured, on one side thereof, a ten toothed ratchet 3| having curved recesses 32 between each of nine of the teeth and a deeper recess 33 between the 1st and 10th tooth for the purpose of carry-over", as described the copending application above referred to. These curved recesses are successively engaged by a lever member 34 to prevent the v counter wheel from over-running.

A spring 35 is provided for retaining the member 34 in engagement with the ratchet wheel 3|, one end of the spring being secured 'to the member and the other end to a metallic block 36 which also forms asupport for the member 34.

The members 34 are positioned and spaced apart by suitable slots in the block 36, and a pin 31 serves as a pivotal support for the members 34.

The block 36 has a cut away portion 36 forming a recess therein. A yoke 33 is pivotally mounted in this depression by means of a pivot pin 40. The yoke 39 has pivoted thereto a pawl member 4| carrying at its upper end a plurality of pawls 42, 43, 44, 45 and 46 of different lengths. A spring 41 is provided to retain one or more of the pawls in engagement with one or more of the ratchets 3|.

A pair of offset arms 48 and 49 are secured together and pivoted in the yoke 39 by means of a pivot pin 50. These arms are secured together at their other end by means of a pin 5| passing through a slot 52 formed in the bar 53. The pin 5| also passes through a slot 54 formed in the links 55. A spring 56, extending from a midpoint of the pin 5|) to a point 51, supported in the metallic block, serves to bring the yoke 39 and the pawl member 4| back to a normal position after the latter has been actuated.

Suitable bearings 58 and 59 are provided on the plate 21 to permit the bar 53 to be reciprocated. The bar 53 is provided with a stop pin 60 to limit its motion in one direction and a stop pin 6| to limit its motion in the other direction.

A spring 62 engages a hole 63 in one end of the bar 53 and has its other end secured to a stud 64 mounted on the plate 21, serving to urge the bar 53 to the right, as viewed in Figures 5 to 9 inclusive, with the stop pin 6| in engagement with the outside of the bearing 59.

A shaft 65 is'journaled in the plate 21, preferably parallel to the shaft 26, and a second shaft 66 is also journaled in the plate 21 adjacent to and parallel to the shaft 65.

A dog 61 is carried by the shaft 65 and is rotated through various portions of a revolution, the position of the slot 54 in the links 55 being varied relative to the slot 52 in the bar 53.

The shaft 66 has secured thereto a lever 69, and the bar 53 carries a stud 10 which is engaged by the lever 59 when the shaft 66 is rotated.

With the shaft 65 in the position shown in Figure 5 the slot 54 in the link 55 is almost parallel to the slot 52 in the bar 53. When the shaft 66 is rotated in a counter-clockwise direction the lever 69 engages the stud I0 and moves the bar 53 to the left to the position shown in Figure 6.

The movement of the bar 53 brings the slots 52 and 54 into alinement, the pin 5| floats freely therein and the pawl member 4| is not actuated, therefore the counter wheels do not move.

When the shaft 65 is rotated to the position shown in Figure 7 the slot 54 isin crosswise relation to the slot 52 so that when the bar 53 is moved to the left the pin 5| is, due to the combined action of the slots 52 and 54, moved in an upward direction to the position shown in Figure 8. In this latter position the pawl member 4|, through the movement of the arms 43 and 49, is

moved upward to advance the counter a value.

Clone)! By referring to Figure 9, in which a group of 'counters is shown, it will be noted that the shaft associated with the first counter and the shaft 85:: associated with the second counter, are in the position shown in Figure 5, and that the shaft 851), associated with the third counter, is in the position shown in Figure 7; accordingly, the slot 54b in Figure 9 is almost at a right angle to the slot 52b and, therefore, when the bar 53 is moved to the left, a counter wheel in the third counter, designated by the numeral 2822, will be actuated and the counter wheels in the first and second counters, designated by the numerals 28 and 28a respectively, will not be affected, although all three of these counters are banked together.

Figures 5 to 9, inclusive, have been included in this application in order that the simple manner of controlling the actuation of the counters can be explained.

In the preferred embodiment of the invention,

the effect of partly rotating the shaft 85 is ac- .complished by a mechanical member electrically selected. Likewise, the action of the shaft 68 and the lever 89 is electrically associated with the movement of an oscillating shaft in the adding machine per se.

Referring to Figures 11 and 12:

The bar 'II is oscillated by an oscillating shaft in the adding machine through suitable linkage which will presently be described. In Figure 11, the counters are identical with those shown in Figures 5 to 9 inclusive. The counter wheel in one of these counters in Figure 11 is designated by 280, the counter wheel in another by 28d and the counter wheel in a third by 280. The other parts of the counters are designated by the same numerals given in Figures 5 to 8 with the exception that the three counters and parts thereof have the additional designation of c, d, or e.

The bar II is provided with suitable guide blocks 12 which are supported on the end plate I4 in such manner that the bar may freely reciprocate thereon. A pivot pin I5 extends through the bar II to a point outside the plate 14. A pair of link members 18 and I1 engage the pin I5, one on each side of the bar, and are retained on the pin by suitable cotter pins I8. A lever I9 is pivotally secured to the links I6 and H by means of a pivot pin 88. Suitable cotter pins, one of which is shown at 8|, pass through the pin 88 at either end thereof to secure the links and the lever 19 in pivotal relation.

A block 82 preferably formed of metal, is supported on a sub-frame 83 and has mounted therein a pivot pin 84. The lower end of the lever I9 is pivoted on the pin 84 and secured in proper relation thereon by means of cotter pins. The lever I9 has pivoted thereto, between the ends thereof, an elongated rectangular member 85, said member being pivotally secured to the lever by means of a pivot pin 86, preferably positioned near one end of the member 85.

The member 85 has a longitudinal hole 81 formed therein and extending from a point near r one end of the member to a point near the other end of the member. A slot 88 is formed in the member 85 communicating with the hole 81. A spring 89 and a hardened metallic block 98 are poitioned in the hole 81 with the block 98 in the vicinity of the mid-portion of the length of the hole. A similar hardened metallic block 9I and a spring 92 are positioned in the hole 81 and oppositely disposed to the first block and spring. The function of these blocks will presently be described.

Referring to Figure 2, the adding machine has a shaft, indicated by the numeral '93, which oscillates each time the adding machine is operated. The end of the shaft 93 opposite to the end viewed in Figure 2, projects from the adding machine and has an extension shaft 94 secured thereto in driving relation as viewed in Figure 14.

A shaft 95 is positioned, preferably at right angles to the shaft 94, in a horizontal plane. A bevelled gear 96 is secured to the shaft 94 in any suitable manner: for example by means of a taper pin 91, and meshes with a bevelled gear 98 which is secured in driving relation to the shaft 95 so thatfor each operating cycle of the adding machine the shaft 94 together with the shaft 95 oscillates in timed relation to a definite portion of said cycle.

A dog 99 is mounted on the shaft 95 in driving relation thereto. The dog 99 has a stud shaft I88 extending therefrom. This shaft projects into the slot 88 formed in the member 85 and is engaged on one side by the block 98 and on the other side by the block 9|.

As the springs 89 and 92 respectively exert an equal presure against the stud shaft I88, motion will be transmitted to the lever I9 through the medium of the member 85 and the pivot pin 85, each time the shaft 95 is oscillated provided none of the mechanism associated with the lever I9 ecomes locked.

In case any of the mechanism does jam the machine will not become wrecked due to the fact that either the spring 89 or the spring 92 is re silient, and the slot is of such length that the stud shaft can move the length of its stroke therein.

In the embodiment shown in Figure 11 the bar 53 is positioned on the opposite side of the plate I4 to that of the bar I I. The bar 53 is supported on suitable bearings 58 and is provided with slots 52, one for each counter.

The arrangement of the offset arms 48 and 49, the pin 5|, the slot 52, the slot 54 and the link 55 is exactly as shown in Figures 5 to 8, inclusive.

The shafts 85c and "660 are provided for controlling entries into the extreme left hand or c counter in Figure 1 the shafts 65d and 6611 are associated with the second or d counter; and the shafts 65c and 56e are associated with the third or e counter. The shafts 65c, 65d and 656 are respectively provided with dogs 61c, 61d and file. These shafts are preferably square, thereby avoiding the necessity of providing keyways therein. The outer end of each of these shafts has a hole formed therein to accommodate a spring I82. Figure 12. Each shaft is provided with an engaging member generally designated by the numeral I83. The engaging member I83 consists of a hollow and dome shaped cup I84, having a square hole I85 formed therein. The cup I84 has secured thereto an arm I86 having a slot I8'I formed therein at the upper end thereof as viewed in Figure 11. The arm I85 has a tail I88 extending therefrom and projecting below the cup I84 as viewed in Figure 11. The bar II is provided with a plurality of studs I89 which project therefrom. in the manner shown in Figure 12. The springs I02 acting against the inside of the cups, normally hold the arms I86 out of engagement with the studs I89.

The operation of the engaging members I83 will presently be described.

An electromagnet H8 is mounted on a suitable supporting plate III and a similar magnet H2 is mounted on a supporting plate II3.

IJU

.of a pivot pin H6 and having an arm H1 extending through a hole H8 formed in the plate III, to engage the domed end of the cup I04.

The armature H5 also has secured thereto, by

rivets or any other suitable means, a piece on insulation H9. A hellcal length of wire I20 and a second helical length of wire I2I are disposed substantially parallel to each other and preferably in light contact with the insulating block II 9. A stationary block of insulation I22 is positioned near the helical wires I20 and I2I and a metallic member I23 is secured to the block I22 in such position that when the armature H5 is in its normal position, as shown in Figure 12, the helical wires I20 and I2I do not make contact therewith.

The magnet H2 has its armature (not shown) arranged in a like manner and provided with an insulating strip and helical wires, in the same manner described for the magnet H0. An arm, associated with the armature H5 of the magnet H2, designated by the numeral I24, engages the domed end of a similar cup.

The arm I24, associated with the magnet H2, would act against the domed end of an engaging member associated with the shaft 656, for example, and the arm H1 actuated by the magnet H0 would control the movement of an engaging member carried by the shaft 66c, for example (it being understood that all of the square shafts 65c, 65d and 658, and 66c, 66d and 66a, are provided with engaging members I03).

The armature and arms associated with any of the magnets H0 and H2 perform two functions:

(a) They shift the engaging members I03 into engagement with the studs I09, and at the same time, (12) They press the helical wires I20 and I2I into engagement with the metallic member I23.

The wires I20 and .I'2I are included in circuits which will presently be described in connection with the circuit diagram of the machine.

In addition to the counters, above described, having counter wheels 28, the device may be provided with a plurality of other counters, generally designated by the numeral I25, and shown in Figures 10 and 11. These counters have counter wheels I28 which are identical to the counter wheel 28 and are mounted on the shaft I26 suitably journaled in the plate I21. The shaft I26 is provided with a keyway in the same manner as the shaft 30 and a pawl I29 engages the keyway I30 in the same manner that the pawl 29 engages the keyway 30. The other parts of the counters I25 are identical with the parts of the first counters described, and like parts of the new counters bear numerals which run 100 higher than the numerals on the parts of the first counters, through the numeral I41.

Instead of the offset arms 48 and 49, the counters I25 are provided with a stud I48. A bar I49 is mounted on suitable supports, not shown, for reciprocation beneath the counters I25 and adjacent to the end of the stud I48. The means for reciprocating the bar I49 will presently be described.

The magnet H0 is The bar I40 is provided with a member I8I- carried on a suitable pivot I62 supported on the bar I49. The member III is provided with a notch I 83, a camming surface I84 and a camming lobe I55. The member III is also provided with a toothed portion I50, and may be retained in one or the other of two extreme positions by means of a toggle spring I51 carried by the bar I48. The member I5I is shown in solid lines in Figure 10 and it will only actuate its associated counter when positioned as shown in dotted lines. The normal position is that shown in solid lines.

The shaft 95 has secured thereto a dog I88 which is in turn connected to an arm I68 by means of a link I60 and pins IGI, I62. The arm I59 has one end thereof pivoted to a bracket I63 by means of a pivot pin I64 passing therethrough. The bracket I63 may be secured in any suitable manner to a support I85 in the machine. A curved link I86 has one end thereof pivoted to the pivot pin I52 and its other end pivoted to the upper end of the arm I59 by means of a pivot pin I 61.

Due to this arrangement each time the shaft 95 is oscillated bythe adding machine mechanism, as above described, the bar I 49 is reciprocated on its supports and the member I5I, carried thereby, is moved relative to the camming stud I48, but when the member I5I is in its normal position, as shown in solid lines in Figure 10, the camming stud I48 is not engaged.

A magnet I68, supported on the frame 14 by a suitable bracket I69, is provided for actuating the member I5I. This magnet is provided with a core I10 carrying a suitable winding and mounted in a shell I1I which forms a return path for the magnetic flux. An armature I12 is pivoted to the shell "I by means of a pivot pin I13 and an arm secured to the armature I 12 is of such proportions that when the armature I12 is in its normal position the member I5I carried by the bar I49 may be retained in its normal position by the toggle spring I51. 1

When the magnet I68 is energized. the armature I 12 is attracted and the motion imparted by the arm' I14 is in turn passed on to the member I5I causing the latter to assume the position shown in dotted lines in Figure 10.

When the member I5I has been actuated and is in the position shown in the dotted lines in Figure 10, the surface I53a of the notch I53 engages the end of the camming stud I48 and, as the bar I49 is moved to the right, as viewed in Figure 10, the yoke I39 is caused to swing upwardly on its pivot pin I40 and one or more of the pawls I 42 to I46 will engage a depression I32 or I33 in the counter wheel I28 and cause the same to add the value of 1.

On the return stroke, in which the bar I49 moves to the left, either the action of the camming surface I54 or the camming lobe I 55 against the camming stud I48 will cause the member I5I to be thrown down to the normal position, shown in solid lines, and so retained by the toggle spring until the magnet I68 is again energized.

The device is also provided with a plurality oi relays I15 having contacts which are closed electrically and which are opened or reset mechanically. One of these relays, (shown diagrammatically in Figure 17) is provided with a magnet coil I16, an armature I11 and an arm I18. The arm I18 is provided with a stud of insulation I19 which, when the armature I11 is actuated, engages a contact arm I carrying a contact point I81 and moves the latter into engagement with a contact point I82 carried by a contact arm I83.

. An arm I84, supported on a pivot pin I85, is adapted to lock the arm I18, the stud of insulation I19 and the contact points I BI and I82 into engagement when the armature I11 is attracted by the magnet I16.

A suitable counterweight I86 is connected to the arm I84 on the opposite side of the pivot pin I85 -to facilitate this action.

The shaft 95 has a disc I81 keyed thereto. A pin I88 is mounted in the disc. A bracke't I89 is secured to the supporting member I and has a pin I99 projecting therefrom in line with the pin I88. A lever I9I is provided with a V-shaped hook which is engaged by the pin I88 during a portion of the oscillating movement of the shaft 95. The end of the lever adjacent to the hook is provided with a camming surface I93, which, acting against the pin I99, when the shaft 95 and disc I81 are moving in a.clockwise direction, as viewed in Figure 1'7, causes the hook I92 to become disengaged from the pin I88. The timing of this disengagement may be set within certain limits according to the positions of the pins I88 and I99.

The lever I9I is pivoted to a bar I94 by means of a pivot pin I95, and an ear I96, formed integral with the lever I9I, has one end of a spring I91 secured thereto for holding the hook I92 and the camming surface I93 in contact with the pins I89 and I99. The other end of the spring I91 is secured to a stud I98 carried by the bar I94. This bar is supported in suitable bearings, one of which is shown at I99, in which it may reciproe cate.

One end of a link 299 is connected to the bar I94, at one end thereof, by means of a pivot pin 29I. The other end of the link 299 is connected to a lever 293 by means of a pivot pin 292. The lever 293 is maintainedin fixed relation to a lever 294 and pivoted on a pivot shaft 295.

The lever 294 has an angular portion 296 which rides a bar 291, and a pin 298 in this bar is normally maintained in contact with the angular portion 296, for example, by means of a spring,

not shown.

A lever 299 consists of a straight portion 2I9, a portion 2i I angular with respect to the portion 2I9, and a portion 2I2 which is preferably spaced apart from and parallel to the portion 2I9. This lever is pivoted on a pivot shaft 2I3 and is connected to the bar 291 by means of a pivot pin 2I4.

When the magnet coil I16 is energized the armature I11 is attracted thereby, the arm I18 through the medium of the stud I19, closes the contacts I8I and 182, and the lever I84 engages and latches the arm I18 to hold the contact points in closed relation, which is shown in Figure 1'7. This occurs during the forward oscillation of the shaft 95.

During the backward oscillation of the shaft 95, which is clockwise as viewed in Figure 17, the pin I88 is in engagement with the V-shaped hook and the pin I99 is in engagement with the surface I93. As the disc I81 moves in a clockwise direction the pin I88 causes the bar I94 to move to the left in its bearings I99. This movement is imparted to the levers 293 and 294 through the medium of the link 299 causing the lever 294 to swing upward in a counterclockwise direction and the camming action of the angular portion 296 against the pin 298 causes the bar 291 to move to the right'as viewed in Figure 17, thereby swinging the lever 299 in a clockwise direction about the pivot 213 whereupon the portion 2I2 raises the counterweight I88 and causes the arm I84 to move downwardly and release the arm I18. The mechanism is so timed and synchronized that by the time thearm I84 is moved downwardly to release the arm I18, the keys have'been reset, the key contacts have been opened, and the magnets H9, H2, have been deenergized, thereby releasing the arms H9 and disassociating the conductors I29, I 2I, from the strip I23. The description of these elements and the circuits associated therewith will be hereinafter described.

The release of the arm I18 permits the contact points I8I, I82 to open and the relay is reset in readiness for another operation. A plurality of multi-contact relays, designated generally by the numeral 2I5, each have magnet coils 2 I6, and an armature 2| 1 in cooperative relation therewith (Figure 18).

The armature has secured thereto an insulat ing block 2I8 carrying a contact pin 2I9 on the upper side thereof, as viewed in Figure 18, and a metallic contact strip 229 on the lower face thereof. The contact point 2I9 and the contact strip 229 are connected together and to a flexible lead 22I (the insulation 2I8 insulating these contacts from the armature 2I1) The relays are each provided with a contact arm carrying a'contact point 223. Normally the armature2I1 is in such a position that the contact points 2I 9 and 223 are in engagement.

An insulating block 224 is positioned beneath the metallic strip 229 and carries a plurality of plungers, one of which is designated by the numeral 225, which is so proportioned that when the armature 2I1 is actuated by the magnet 2I6 all of the plungers 225 are connected in common by means of the metallic strip 229.

In order to take care of any inequalities in the surface of the strip 229 and also in order to effect a slight wiping contact between the plungers 225 and the strip 229, the plungers are each provided with a spring 226 for urging the plungers upwardly as viewed in Figure 18. Each plunger is provided with a shoulder 221 for limiting its extreme upward movement. The lower end of the spring bottoms against a metallic member 228 in the block 224, and each metallic member extends downwardly from the block 224 to facilitate making electrical connections thereto.

In the embodiment of the relays shown in the present application, it has been found preferable to employ ten plungers 225 to .each relay. The arrangement of these plungers relative to each other is shown in Figure 19.

Referring to Figures 14, 15 and 16, the device is provided with an on key 229 for operatively associating the mechanism with the adding machine mechanism, and an off key 239 for disassociating the mechanism from the adding machine mechanism. The hub 23I of the bevelled gear 98 is faced off and is provided with a hole 232 parallel to the shaft 95 and forms the stationary half of a clutch.

The shaft 95 is provided with a long key 233. A collar 234 forms a working fit on the shaft 95 and is provided with a keyway (not shown) which rides on the key 233. The collar has a groove 235 formed therein, and the face of the collar adjacent to the hub 23I is provided with a pin 236 extending therefrom in parallel to the shaft 95, which, when the clutch is engaged, fits into the hole 232 and transmits motion from the gear 98 to the shaft .95.

The on key 229 is secured to a shaft 231 which is supported in suitable bearings 239, which is in turn supported by a bracket 239 cccured to the base or supporting member I96.

The shaft 231 has secured thereto an arm 249 and an arm 2 which together might constitute a fork, one of these arms being positioned on each side of the collar 234. vThe arm 249 is provided with a pin 242 which engages the groove 235 on one side of the collar and the arm 2 is provided with a pin 243 which engages the groove 235 at a point opposite the pin 242, so that when the on key 229 is depressed, the collar 234 is moved into engagement with the hub 23! and with the pin 236 positioned in thehole 232 thereby placing the shaft in driven relation to the gear 98.

The shaft 231 also has secured thereto a collar 244 having a stud 245 projecting therefrom. The stud 245 extends between a pair of contact arms 246-441 and a second pair of contact arms 248-249. When the on key 229 is depressed, the shaft 231, as viewed in Figure 15, is moved in a counterclockwise direction and the contact arms 249-249, which are normally in contact with each other, are opened, and the contact arms 246, 241, which are normally open, are brought into contact with each other.

The function of these contact arms will presently be described in connection with the circuit diagram of the device.

The shaft 231 is also provided with an arm 259 and has a notch 25! formed near the outer end thereof, as viewed in Figure 16 and in line with the off key 259 in Figure 14. This notch is made in the form of a V and is engaged by the upper end of the lever 252. A lever 252 pivoted on a pin 253 is mounted preferably in a vertical plane and normally, when the key 229 has not been depressed, rests against the end of the arm 259 engaging the notch 25!. A spring 254, having one end secured to the lever 252 and the other end secured to a stud 255, suitably supported on the frame, urges the lever 252 against the end of the arm 250.

When the on key 229 is depressed, the lever 259 is moved upwardly as viewed inFigure 16 and the upper end of the lever 252 engages the notch 25| and retains the key 229 in its depressed position, at the same time retaining the clutch members 23! and 234 in engagement.

The off key 239 is pivotally mounted on the shaft 231 and has extending therefrom an arm 256 carrying a camming member 251. The camming member is of such form and so positioned that when the ofi" key 239 is depressed, the lever 252, which is engaged by the camming member 251, by this action, is disengaged from the notch 25l and moved to the right as viewed in Figure 16, thereby permitting the clutch members 23l, 234 to become disengaged and, in effect, disconnecting the shaft 95 from the shaft 94 which is driven by the adding machine.

At the same time, due to the presence of the pin 245 between the contact arms, the contact arms 246, 241 are opened and 248, 249 are closed.

A pair of contact arms 258, 259 is mounted on the lever 19, Figure 11; a pin 269, Figure 11, Figure 15, and Figure 22, is carried by a Bakelite link 261 and extends between these contact arms. This link has a hole formed therein at one end thereof fitting the stud shaft I90. The other end of the Bakelite link 26l is re'ciprocably supported on the member 85, adjacent to the end of the latter, which is secured to the lever 19, a slot 262, formed in the member 85, being pr vided :0 t is purpose.

In case of any Jamming of the mechanism associated with the bars 69 or 1|, as above dee scribed, the spring 89 or the spring 92 will compress, due to the movement of the stud shaft I99 and the lever 19 will not be actuated when this occurs, the movement of the stud I99 is imparted to the pin 269 through the medium of the Bakelite link 26l, and thereby the contact arms 269 and 259 are separated to open the circuit, as will presently be described.

When the machine operates normally the lever 19 moves with the stud shaft I99 and since the contact arms 258, 259 are mounted on and moved with the lever 19 these contact arms are not opened. In other words, they remain normally closed until such time as the mechanism 'might become jammed, whereupon they open and disable the circuits in .the machine.

In the present embodiment of the invention, the "units, tens and hundreds keys, in the adding machine, are each provided with a pair of contacts which are normally open and which are closed when the key associated therewith is depressed.

One row of these contacts is shown in Figures 2 and 210 and designated by the numerals 263 and 264. Each key of the adding machine in the units, tens and hundreds row, in addition to controlling the movement of a differential stop bar 265, also closes a'pair of contacts 263, 264 associated therewith, and maintains them in this relation until the reset cycle in the adding machine occurs. The ky is maintained in the depressed position by means of the action of a slidable control member 266 in the usual manner. Each slidable control member 266 is provided with a curved end 261 which engages an upstanding projection 268 formed integral with a yoke 269. As these machines are well known in the art their functions will not be described in so far as the adding machine per se is concerned.

A rocking member 219 includes a forked portion engaging a shaft 21l and has secured thereto a contact actuating member 212 which presses against a movable contact member 213 and shifts the position of the latter each time the member 219 is rocked. Referring to Figure 3, the contact member and its associated contact arms are shown enlarged for clarity.

The movable contact member 213 consists of a contact arm 214, a second movable contact arm 215 tied together with a bar of insulation 216. A spring 211 has one end thereof secured to the bar 216 and the other end is secured to a stationary member in the adding machine, designated by the numeral 218, at the point 219. The point 219 is so positioned that when the bar, together with the arms 214 and 215, are on one side of the center line, the arm 215 is maintained in contact with a stationary contact arm 290, and the contact arm 214 is maintained in contact with a station ary contact arm 28L The end of the actuating member 212 acts against the bar 216 and swings the contact arms 214 and 215 in a clockwise direction, as viewed in Figure 3. When dead center is passed the spring 211 propels the contact arm 215 into contact relation with a stationary contact arm 292 and the contact arm 214 into contact relation with a stationary contact arm 283. These contact arms and contact members maintain a zero circuit, which will presently be described in connection with the circuit diagram.

As will be pointed out presently in connection with the circuit diagram, some of the differential which is shown diagrammatically in Figure 20.

The counter wheels are designated by the numejrals 28, a sheet of paper by the numeral 284, and a sheet of carbon or ribbon by the numeral 285. A stationary member 288 may be secured to the device in any suitable manner and a bar 281 is arranged to reciprocate thereon. The bar is provided with a plurality of slots 288 each having an associated pin 289 secured to the stationary member 286. The bar 281 also carries a plurality of shafts 298, 298a, one for each row of counter wheels 28. Each shaft 298 carries. a platen roller 29!.

A contact arm 292 and a cooperating contact arm 293 are insulatedly supported on the stationary member 286. The contact arm 292 is so mounted, relative to the contact arm 293, that it tends to open the contact points 294 and 295. The contact arm 292 carries a camming member 296 which is engaged by the platen roller 29! when the bar 281 is in its extreme upper position, as viewed in Figure 20, thereby maintaining the contact points 294 and 295 in contact with each other.

When it is desired to print, the bar 281 is moved downwardly. During the first portion of its movement downwardly, due to the sliding portion of the slots, the platen rollers are moved over to the left in the vicinity of the counter wheels 28.

Further movement of the bar 281 downwardly is straight and parallel to the counter wheels due to the straight portion of the slots 288,-causing the platen rollers 29l, 291a to pass over the surfaces of the counter wheels 28 and thereby impressing on the sheet of paper visible characters which constitute a record of the values entered into the counter wheels.

Due to the downward movement of the bar 281 the platen roller 29l is disengaged from the camming member 296 thereby permitting the contacts 294 and 295 to become separated and disabling the electrical circuits in the device as will later be pointed out.

Each counter is provided with a gear or pinion 452 keyed to its shaft. Racks (not shown) mesh with these pinions and are provided so that the counter shafts 26 and I26 may be rotated forward to reset the counter wheels. When the shafts are rotated forward the keyways 38 and I38 engage the pawls I29 within the counter wheels and thereby the counter wheels are reset to For the convenience of the operator, the device is built into a table or desk 291 having a depressed portion 298 formed therein to support the adding machine 299. The top of the desk is provided with doors 388, 38! and 382. The shaft 94 extends from the right side of the adding machine into the compartment below the door 388 and a portion of the shaft 95 is also accessible through the door 388.

The counters and the printing mechanism are accessible through the door 382 while the relays and other control devices are accessible through the door 38L Referring to Figures 21a, 21b and 21c, which, together constitute a circuit diagram of the device, it will be noted that the contact points 263 associated with the row 383 of units keys are individually connected via the cable 384 to a corresponding lower magnet H2 in each of the banks of magnets 385, 386 and 381. For example, clarifying this, the contact 263 associated with the 1 key in the units row is connected to the 1 magnet in the bank 385, to the 1 magnet in the bank 386, to'the 1 magnet in the bank 381, etc.

The portion of the zero circuit associated with the "units keys, which is normally effective when none of the-units keys, 1 to 9, have been operated, has the contact arm-288 connected via the same cable 384 to one side of the 0 magnet in the bank 385, and to one side of the 0 magnet in the bank 386. The contact arms 264, which cooperate with the contact arms 263, are connected in common by means of a wire 388, which in turn is connected to other wires which will presently be described.

5 The contact arms 263a associated with the row 389 of tens keys are each connected via a cable 3l8 to one side of corresponding upper magnet coils H8 in the banks 3, 312 and 3l3. For example, the contact arm 263a, associated with the "5 key in the tens row is connected to one side of the 5 magnet in each of the groups 3, 3I2 and 3l3.

The contact arm 288a, which forms a part of the zero circuit, normally closed when none of the tens keys in the row 389 have been depressed, is connected via the cable 3I8 to one side of the 0 magnet in each of the banks 3| I, 3l2 and 3l3.

The contact arms 264a in the tens row, which cooperate with the contact arms 263a, are all connected in common by means of a wire 3l4. The other sides of all of these magnets are connected as follows:

The return wires of the magnets in the bank 3 are each connected by a cable 315 to a group of plunger contacts 225 in the block 224. The contact strip 228 is connected by means of a wire 3I6 to the contact arm 222d. The contact arm 222,, which is normally in contact with the contact strip 228, is connected by means of a: wire 3| 1, to the contact strip 2281).

The return Wires of the magnets in the bank 385 are connected by means of a cable 3! to the plunger contacts 225a in block 224a. The contact strip 228a is connected by means of a wire 3|9 to the contact arm 222e. The contact strip 228e cooperating therewith, is connected by means by a wire 328 to a resistor 32l. This resistor is connected through a series of circuits, which in turn connect to the positive side of the line. This series of circuits may be traced as follows:

From the units resistor 32I to a bus wire 322, via a wire 323, the contact arm 293, thence via the contact points 294 and 295 to the contact arm 292. From the contact arm 292 current is led by a wire 324 by the contact arm 258, thence to the contact arm 259 and via the wire 325 to the contact arm 246. When the on key 229 is depressed the contact arms 246 and 241 are in contact further current will flow from 246 to the contact arm 241 and via the wire 326 to one of the center contacts 328 of the double pole, double throw switch 321, from which it passes via the plate 329 to the switch contact 338 and via the wire 33| to the contact 332 of the double pole. double throw switch 333, thence via the 'plate 334 to the center contact 335, and via the wire 336 to the positive side of the line.

As described above, it is preferable that the circuits to the counter magnets be disabled during a printing operation. Accordingly, this circuit will be interrupted 'by the opening of the contact arms 292, 293 during a printing operation.

It is also described above that the circuits should be disabled in case the mechanism becomes ,hung up. This is effected by separating the contact arms 258 and 259. It was also pointed out above, in connection with Figures 14, 15 and 16, that when the of! key 230 was depressed, the contacts 246 and 241 are interrupted.- As these contacts are included in this circuit it is obvious that the opening of these contacts will disable these circuits.

The return wiresof the magnets in the bank 3I2 are connected via -a cable 331 to the plunger contacts 22511. The contact strip 220d is connected via a wire 338 to the tens" resistor 339 which is in turn, connected to the bus wire 322.

The contact arm I93a is connected via a wire M3 to the contact arm I801). The contact arms I831), I83h and I839 are connected together by means of a wire 4I4 which is in turn connected to a contact arm 4I5 associated with the grand total key 2,

The other terminal of the motor 409 is connected via a wire 4I6 which is in turn connected to a wire 4I1 leading to the negative side of the source of current.

The wire 4!! is also connected to a contact point 4| 8 of the switch 333. A plate M9 is provided for connecting the contact point 4| 8 to the contact point 420. The wire 42I connects the contact point 420 to a contact point 422 of the switch 321.

A plate 423 is provided for connecting the contact point 422 to a' contact point 424. A wire 42! connects the contact point 424 to the wire 399 above described which connects the helical wires 121 and 120a together and to the sub-total key and the motor bar. The other terminal of the magnet 116k is connected by means of a wire 426 to one side of the sub-total counter magnet 168k and to the contact arm 436 associated with the sub-totalkey 400.

The otherterminal of the magnet 1169 is connected by means of a wire 421 to one side of a miscellaneous counter magnet 169g. The wire 421 branches and connects via a wire 428 to contact points 2930, 283d, 283e and 263f, and to contact points 429, 430 and 431 associated with the switch 354, and 432, 433 and 434 associated with the switch 356.

The other sides of the total bills counter magnet 168, the sub-total counter magnet 168k, and the miscellaneous counter magnet 168g are connected by means of a wire 436 to a limiting resistor 431. The other side of the limiting resistor is connected to the bus wire 322.

The statistical mechanism is disconnected from the adding machine by depressing the oil? key 230. The contact points 246 and 241 are opened and the contact points249 and 249 are closed. This last pair of contact points permit the current to flow to the motor so that the adding machine can be operated by means of its motor bar 402 in the usual manner, when a statistical count is not desired.

Where alternating current mains only are available to supply current to the machine, a suitable rectifier (not shown) may be provided for changing the alternating current into direct current, in which case the negative lead from the rectifier would be connected to the contact point 441 of switch 333 and also to the contact point 448 of the switch 321. The positive lead from the rectifier would be connected to the contact point 44.9 of the switch 333 and also to the contact point 450 of the switch 321.

In this case, the switch blades would be thrown so that the blade 334 connects the switch contact 335 to the contact 449. The blade 419 would connect the contact 418 to the contact 441 in the switch 333. In the switch 321, the blade 329 would connect 320 to the contact 450 and the blade 423 woud connect 424 to the contact 448.

The last row of keys to the left (the hundred thousand row), in the adding machine, designated by the numeral 446, might be termed the zero-zero" keys, and when any key in this row is actuated the contact points 280gand 283g are closed.

Whenever a customers billshows the non-use of current (during the conducting of a rate study) it is required to record No bill, in which case the 0 or zero-zero counter should be actuated. This is accomplished as follows:

When any of the keys in the row 446 is depressed, as pointed out above, the contacts 280g and 2939 are closed, thereby establishing a circuit v which may be traced as follows:

The wire 438, which extends from one terminal of the 0 magnet in the nank 301 to the contact arm 283g, is connected via the contact arm 2809 to the wire 443, which is in turn connected to one side of the 0 magnets in all of the other banks of magnets via the contact arms 214a, 280a, and the cable 350, and via the contact arms 214, 280 and the cable 304.

The wire 443 is also connected via the contact arms 2141), 2811b and the cable 310 to the zero contact 311 in the switch 352. The blade 385 connects the switch contact 311 to the contact 360. The wire 359 from the contact 360 is connected to one terminal of the magnet 2115b. The circuit from the other terminal of 21Gb leads via the wire 358, the magnet 345 and thence via the wire 351 to one terminal of the magnet 2160, from the other terminal of the magnet 2160, a wire 341 connects to the bus wire 323, to the platen contacts 294, 295 and via the wire 324 to the yield contacts 258, 259, thence via the wire 325' to the on contacts 246, 241, thence via the wire 326 to the center contact 328 of the switch 321, and via the switch blade 329 to the contact 330. Leaving the contact 330 the circuit extends via the wire 331 to the contact 332 of the switch 333, via the blade 334 to the contact 335, and via the wire 336 to the positive terminal of the source of current.

After depressing the zero-zero key, as above described, the motor bar 402 is depressed, thereby closing the contacts 401, 401, after which the circuit extends from the wire 3 via the contacts 280e, 2140, 280d, 214d, 280e, 214e, 280 214 and via the wire 40 8-to the contact 401, thence to the contact 401 and via the wire 3% to the helical wires 120a and 121.

A wire 425 connected to the wire 398 leads through the switch 321 via the contact 424, the blade 423, the contact 422 and from 422 via the wire 421 to the contact 420, the blade 419 and the contact 418 of the switch 333, and thence via the wire 411 to the negative side of the source of current.

As the act of depressing the motor bar, after the depression of one or more of the adding machine keys, completes the circuit as above traced from one polarity of a source of current to the the depression of a zero-zero key. This circuit may be traced as follows:

From the bus wire 322 above described, via the limiting resistor 32I and the wire 320 to the contact strip 220e, thence via the contact arm 222a and the wire 3I9 to the contact strip mm, and to the contact arm 222a. From the contact arm 222a the circuit leads through the wire 343 to the contact strip 2200. Since the contact strip 2200 is in contact with the ten plunger contacts 226e, one side of all the magnets in the bank 301 is connected to the bus wire 322.

The magnet in the bank 3I3, as well as the 0 magnets in all of the other banks, has one terminal thereof connected to the wire 443 as above described.

Due to the contact established between the strip 220?) and the plunger contacts 2251), when the magnet 2| 6b was energized, connection to the other side of the magnet coils in the bank 3I3 may be traced as follows:

From the bus wire 322 via the limiting resistor 339 and the wire 336 to the contact strip 220d and via the contact arm 222d and the wire 3I6 to the contact strip 220, thence via the contact arm 222 and the wire 3" to the contact strip 220b, thence via the plunger contacts 2261) and via the cable I to one side of all the magnets in the bank 3I3. Since the 0 magnet is the only' one in this group to have its return circuit completed, it is the only one in this group which will be actuated. As a result of the depression of the motorbar the 0 magnet in the bank 301 and the 0 magnet in the bank 3I3 are actuated with the result that the 0 counter is selected for actuation.

The 0 magnet in the bank 3I3 may be considered to correspond to the magnet IIO shown in Figure 13 and the 0 magnet in the bank 301 corresponds to the magnet H2. The arm II1 associated with the armature II acting against the domed end of the cup I04, associated with an engaging member I06 carried by the shaft 66a, for example, and the arm I24 associated with the magnet II2 will act against the domed end of the engaging member carried on the shaft 66s, the shafts 65c and 66e being assumed to be associated with the 0 counter.

At the same time, the helical wires I20 and I2I are moved into engagement with the metallic strip I23 and the helical wires I20a and I2Ia are moved into contact with their associated metallic strip I23. The relays I16a. and H611 are energized due to the establishment of contact between the helical wires-l20a., I2Ia and/or I20, I2I, respectively. The circuit through I16a may be traced as follows:

From the bus wire 322 via the limiting resistor 394 and via the wire 393 to one terminal of the magnet I16a. From the other terminal the circuit may be traced via the wire 392 to the helical wire I2Ia thence via the contact strip I 23a. to the helical wire I20a and via the wires 398, 426 through onegside of the switch 321 and via the wire 42I to one side of the switch 333 and via the contacts and blades in one side of this switch and the wire 4" to the negative side of the source of current, therethrough the relay I16a is energized. The circuit through the contacts of this relay will presently be described in connection with the adding machine motor circuit.

The relay I16b is energized as follows:

Current flows from the bus wire 322 via the limiting resistor 391 and the wire 396 to one terminal of the magnet I161! and out from its other terminal via the wire 396 to the helical wire I20 and thence via the contact strip I23 to the helical wire I2I and via the wire 398, one side of the switches 321 and 333 and via the wire 4I1 to the negative side of the line, thereby energizing the relay I16!) and closing its contacts I80b and I83b.

As above described, when the relay I16a was actuated, its contacts I80a and I63a were closed. The closing of both of the contacts of both of these relays established a circuit to the motor 409 of the adding machine which may be traced as follows:

From the positive side of the line, via the wires 336, 446, 46I and 4 to the contact arm I83b, thence to the contact arm I 80b and via a wire 3 to the contact I83a. From the contact arm I83a current flows to the contact arm I80a and via the wire 4I0 to one side of the motor 409.

-From the other side of the motor current flows via the wire 4I6, the wire 4H and to the negative side of the source of current. Therefore, as soon as the 0 magnet in the bank 301is actuated, closing the circuit to the relay I16b, the motor 409 operates, thereby actuating the adding machine and motion is transmitted via 93, Figure 14, to the shaft 94 and via the gears 96 and 98 to the shaft 95,. Figure 11, and via the yield member t0 the lever 19 and thence via the link 16 to the bar 1I.

Since the engaging member associated with the shaft 65a of the 0 counter and the engaging member associated with the shaft 66a of the 0 counter, have been actuated by the magnets H0 and H2, as above described, and are in engagement with pins I09, the movement of the bar 1I will actuate the 0 counter and cause the same to add a 1. This action has been previously described in connection with the description of Figures 5, 6, '1, 8, 9 and 11.

One of the counters, of the type shown in Figure 10, is provided to count the total number of bills handled during a rate study and accordingly it also will be actuated due to this operation. Ijhe magnet controlling this counter is designated by the numeral I68 and its circuit may be traced as follows:

From the bus wire 322 via the limiting resistor 431 and the wire 436 to one terminal thereof and from the other terminal via the wire 406 to the contact arm 401 of the motor bar, and thence to the negative side of the line, as above described.

Assuming that the next customers bill is for $1.95, the 1 key would be depressed in the row 369, the 9 key in the row 309 and the 5 key in the row 303.

Taking the row 303 first for purposes of description, the contacts 263 and 264 associated with the 5 key would be closed and the release of the differential stop bar and mechanism associated therewith would open the 0 circuit above described, thereby connecting one side of the 5 magnets in the bank 305, 306 and 301 to the motor bar contact arm 401, the connection being via the cable 304, contacts 263 and 264 associated with the 5 key (in the row 303) via the wires 306, 442 and 443, the contacts 280e, 2140, 280d, 214d, 280e, 214e, 280), 214) and thence via the wire 408 to the contact arm 401.

The depression of the 9 key, in the row 309 closes the contacts 263a and 264a associated with this key and the portion of the 0 circuit associated with the diiferential stop bar of this row; causes the contact arm 214a to break contact with 280a and to establish contact with 233a, thereby disabling the "tens portion of the zerd'cirouit. Due to the closing of the contacts "In and'264a associated with the 9 key, one side of each of the 9 magnets in the banks 3H, 3 and M3 to the motor bar contact arm 401.

When the 1 key in the row 359 is depressed, the

contacts 230D and 2141) are opened and the con- .tact arms 25317 and 264?: associated with the 1 key are closed, thereby, via. the cable 310, connecting the center contact 312 of the, switch 352 to the motor bar contact 401.

The contact 312 is also connected by the switch blade 334 to the contact 351 which is in turn connected via the wire 350 to one terminal of the magnet 2| 6d. From the other terminal of the magnet 2I6d a wire 34! leads to the magnet 346 and thence via the wire 343 to one terminal of the magnet M66. The other terminal 2|6e is connected via the wire 341 to the bus wire 322.

Current flowing through the magnets 2|6d, 343 and 2 lie causes the metallic strip 220e to contact the plunger contacts 225e and also cause the contact strip 220d to contact the plungers 225d. When this occurs, current will flow from the bus wire 322 via the limiting resistor 32! and a wire 320 to the contact strip 220e. Since the plungers 225e are connected via the cable 340 to one side of each of the magnets 306, and since the magnet in this bank is the only magnet to have had its return circuit completed, this magnet will become energized.

Current flows from the bus wire 322 via the limiting resistor 339 and the wire 333 to the contact strip 220d and via the plunger contacts 225d, with which the strip is in contact, through the cable 331 to one side of each of the magnets in the bank 3 i 2.

Since the 9 magnet is the only magnet in this group which was energized when the 9 key in the row 309 is depressed, this magnet in the bank, only, will be energized.

The 9 magnet in the bank 3l2 actuates an engaging member associated with one of the shafts 66, and the 5 magnet in the bank 306 actuates an engaging member carried on a shaft 65c, these engaging members being associated with the 9 magnet and 5 magnet aforesaid, respectively, and the operation of these two specific engaging members associates a 95 counter in a group of counters designated as hundreds counters (containing counters from 100 to 199) The actuation of the 1 key in the hundreds column 363 actuates the relays 2l6d; 246 and 2l6e and causes the selection of the counters in the one hundred group above mentioned.

If the 2 key in the hundreds" column had been depressed, instead of the 1, the contact 313 of the switch 352 will have been connected instead of the contact 312, in which case the relays 2", 344 and 2l6a would have been selected, due to the fact that the wire 365 fitting the relay 2|6, is connected to the contact 366 and the switch blade 303 connects 313 to 366.

If the amount had been $.95, instead of $1.95, the 0 contact arms 2801) and 214b would not have been opened and the contact 21! would have been connected to the wire 443, thereby selecting the relays 2| 6b, 345 and 2 160 through the medium of the wire 359 as above described in connection with the recording of a no bill.

It must be borne in mind'that counters recording amounts from 0 to 99 are selectively associated with the mechanism by means of any combination of magnets in the banks 301 and M3, the selection of which magnets isin turn controlled by the relays 216b, 345 and 2| 6c. Counters recording amounts from 100 to 199 are selectively associated with the mechanism by means of any combination of magnets in the banks 306 and M2, the selection of which magnets is in turn controlled by the relays 216d, 346 and 2l6e. Counters recording amounts from 200 to 299 are selectively associated with the mechanism by means of any combination of magnets in the banks 305 and 31 I, the selection of which magnets is in turn controlled by the relays 2| 6, 344 and HM.

When the switches 352, 354 and 356 are connected, as shown in the circuit diagram, bythrowing the blades of the switch 352 to the left, as viewed in the diagram, and by throwing the blades of the switch 354 to the right, as shown in the diagram, the 0. to 99 counters may be made to record bills in amounts from 300 to 399. The

' 100 to 199 counters may be made to record bills in amounts from 400 to 499; and the 200 to 299 counters may be made to record bills in amounts from 500 to 599.

If it is desired to go higher, the blades of the switch 352 may be allowed to remain thrown to the left, as just described; the blades of the switch 354 may be thrown to the right, in which case the 0 to 99 counters may be made to record bills in amounts from 600 to 699, the 100 to 199 counters may be made to record bills in amounts from 700 to 799, and the 200 to 299 counters may be made to record bills in amounts from 800 to 899, etc.

In making a rate study, in the range from 0 to 299, in case some larger bills appear in the group, they are automatically thrown into the miscellaneous counter which is controlled by the magnet l68g. In that case, the switches 352, 354 and 356 are positioned as shown in the diagram, in which the contacts associated with the 300 to 899 keys inclusive are connected by the cable 310 to the center contact of the switches 354 and 356 and via the blades of these switches to the contacts designated as miscellaneous, which are all connected together, and are in turn connected via the wire 428 to the magnet 168g controlling the miscellaneous counter.

It must be borne in mind that each bank of. counters contains a group of 100 counters. Ten upper magnets H0 and ten lower magnets H2 control the selection of any one of the hundred counters in a bank of actuation. For example, a 0 magnet in the upper row and a 1 magnet in the lower row will effect the selection of a 1 counter. On the other hand, a 1 magnet in the upper row and a 0 magnet in the lower row will select a counter. An 8 magnet in the upper row. and a 9 magnet in the lower row will select an 89 counter, whereas a 9 magnet in the upper row and an 8 in the lower row will select a 98 counter.

It is obvious that the adding mechanism can be omitted, and a driving mechanism substituted therefor, in which case the keys would control the selective association of the counters with said mechanism; in cases where totalizing the amounts of the bills is not desired, or where they are totalized otherwise.
